Abstract: ABSTRACT OF THE DISCLOSURE          A tape counter for counting an amount of tape by which a tape has run for a video signal recording and reproducing apparatus and method therefor, in which the number of frames on tape tracks over which each rotary head scans are counted according to a change in level of an envelope of a reproduced FM signal detected through each rotary head, the number of rotations of a rotary drum on which the rotary head is mounted is counted, and the amount of tape by which the tape has run is counted on the basis of the number of frames scanned by the rotary head and the number of rotations of the drum. The tape counter detects the amount of tape by which the tape has run in all running modes during a reproduction operation with a high accuracy and displays the amount of tape by which the tape has run in a series of units of hours, minutes, and seconds.

Abstract: INVENTION:  APPARATUS FOR WINDING-UP AND UNWINDING    CONTINUOUSLY ARRIVING FLEXIBLE FLAT STRUCTURES     ABSTRACT OF THE DISCLOSURE     A substantially ring-shaped or annular winding core serving for the reception of a package of products wound thereupon is frictionally mountable at its substantially cylindrical inner surface upon drivable support wheels and can be again lifted-off such drivable support wheels.  At the inner surface of the mounted winding core there can be placed into operative position beneath the support wheels an essentially freely rotatable guide wheel.   This  freely rotatable guide wheel prevents lift-off of the winding core from the support wheels and can increase the friction which prevails therebetween.  In order to be able to use winding cores having a purely cylindrical smooth inner surface and during the rotation thereof to nonetheless ensure for an exact positioning in axial direction, the guide wheel is deflectable in its operative position about a deflection axis which is radially directed with respect to the mounted winding core, which imparts to the rotating winding core an axial movement component, and an impact or stop arrangement is provided for limiting such axial movement.

Abstract: TITLE    METHOD OF MAKING CERAMIC COMPOSITE ARTICLES BY INVERSE SHAPE REPLICATION OF AN EXPENDABLE PATTERN                         APPLICANT              LANXIDE TECHNOLOGY COMPANY, LP                         INVENTOR                Andrew Willard URQUHART Evans Allen LAROCHE, JR.                         ABSTRACT     There is disclosed a method of producing a self-supporting ceramic composite body having therein at least one cavity which inversely replicates the geometry of an expendable pattern.  The method includes the steps of surrounding the expendable pattern with a filler material to thereby form a filled cavity within the filler material.  The expendable pattern is chemically or physically removed from the filler material and a quantity of a parent metal is put into the cavity.  The parent metal is heated to a temperature above its melting point and an oxidation reaction process begins whereby the oxidation reaction product infiltrates and embeds the surrounding filler material.  Excess filler material and/or excess parent metal are removed, thus resulting in a self-supporting ceramic composite body having a cavity in the shape of the expendable pattern.

Title: Blood pressure monitoring method and apparatus
Inventor: ECKERLE JOSEPH S
IPC: G06F17/00
Filed: 1988-01-14
Granted: 1993-10-12
Abstract: Abstract Intraarterial blood pressure is measured noninvasively by an electromechanical transducer (22) that includes an array of transducer elements (22-1 through 22- 19).   The transducer extends across an artery (24) with transducer elements at the ends of the array extending beyond opposite edges of the artery.  A set of diastolic and/or systolic pressure and pulse amplitude values is obtained from the outputs from the transducer elements,  which values are   stored in computer (62).   Information concerning the subject related to the diameter of the underlying artery including, for example, the subject's  age, weight, arm and wrist diameter also is entered into computer (62) through keyboard (64), from which information an estimation of the diameter of   the underlying artery is obtained.  Using the set of pulse amplitude values, a transducer element at the center of a search ares located substantially at the center of the artery is identified.  A center of gravity a two humps and/or a curve fitting method may be used to identify the transducer element at the center of the search area.  A group of transducer elements that overlies the artery of estimated diameter then is identified.  Using outputs from only said group of transducer elements, one transducer element having a local minimum of one of the diastolic and systolic pressures,  relative to  the transducer at the center of the search area, is identified, which transducer element is selected for monitoring blood pressure.

Abstract: A preproofed, and already partially baked crusty bread which is frozen for later completion of  baking and a method of manufacturing the same.  When desired to be served, the end user merely takes the product out of the freezer and places the same in the oven for completion of baking.  The shelf life  of the  product  is  commercially  significant whether the product  is in  the frozen state or thawed and refrigerated or even thawed and retained at room temperature until  ready to be baked.   After baking is completed,  the freshness of  the product  is retained for up to about 24 hours.  A critical aspect of the method of manufacturing the product is a second injection of steam into the oven during partial baking of the product, which provides the end user with a completely sealed crusty bakery product that will not have the crust separate from the loaf.  The injection of the steam  is  a  second  injection  of  steam  and provides  the product with about 20% or greater of moisture than a fully baked and then frozen product.

Abstract: ABSTRACT OF THE DISCLOSURE           A garment to be worn conveniently and comfortably over the upper body of a seagoing person to gain protection from rain, wind, and/or cold, which includes an interior deflated fluid tight enclosure, i.e. a bladder, to be very quickly inflated inside the garment in a time of emergency.  The deflated fluid tight enclosure covers at least the interior upper back portion of this garment and also covers at least the interior of the right and left chest portions of this garment.  An inflating subassembly is operatively secured between the deflated fluid tight enclosure and to either the right or left chest portion of this garment.  This inflating subassembly has an alternatively usable month and lung inflatable valved air intake-discharge communicating with the deflated fluid tight enclosure, and an alternatively usable filled compressed fluid valved cylinder discharge also communicating with the deflated fluid tight enclosure and having a coilable pullable lanyard.  Then a pocket like subassembly is removably secured, by using loop and hook fasteners on the exterior of the garment at either the right or left chest portion and is non removably secured to the coilable pullable lanyard.  This pocket like assembly fully covers and protects the inflating subassembly, until an emergency, when the seagoing person intentionally, readily, and quickly, pulls the pocket like assembly away from the garment, causing the pulling of the lanyard to activate the valve on the compressed fluid valved cylinder.  The fluid tight enclosure is then quickly inflated, creating the buoyancy needed by this seagoing person.
